Make sure you have a logo, screenshots and some descriptive text ready for the app submission

A version of your .app file that has been compiled for Release.

Decided how you are going to licence your app. The app store itself allows you to define how the app will be licenced, will it be free, will it be per purchase, per user, will there be a trial etc. Some of these decisions are not simple and require significant forethought and in some cases additional development work. For our app I decided to keep it simple and go for a free version. Microsoft published a couple of great blogs / articles helping with the licencing over at the Office apps blog.

Finally, make sure you have tested, tested and tested your app again, the submission process is very thorough and tests the functionality of your app across not only IE but all supported SharePoint 2013 browsers.

Once all of the above is ready, submitting your app is relatively simple. Navigate to the Seller Dashboard and follow the prompts to submit the app.

First choose a listing type, our app is for Project Server, so we need to choose an app for SharePoint, then click on next.

In the next screen you will be asked some information about your app like the name, version, category to list it under and some other bits and pieces. The most important part are the testing notes, these are your only real way of passing information through to the testers who are looking at your app.

As we are making the app available to everyone, there is no need to choose Trial support. Click on Next.

The final bits to add before you can submit the app are screenshots and some descriptive text and links to support, EULA and Privacy policies.

Once you’ve added that text, click on Next and your ready to submit for validation.

From experience, the validation process can take around 3-5 working days. Unfortunately at the moment there is no progress indicator of where you are in the process, with the app either being in a ‘Draft’ or ‘Approved’ state.

Once the app has become approved, it takes a few hours for it to propagate down into the SharePoint app store and to become available for everyone to download and start using.

In conclusion

I hope these posts have shown you that creating an app for Project Server, or for that matter, SharePoint in general is really really simple. Through the various options for hosting apps, either in SharePoint, in Azure, or on your own infrastructure and the investments in APIs such as oData, Rest, JSOM & CSOM, there is an incredibly powerful set of tools available for you to leverage. As we saw, you don’t need expensive tools, with Microsoft making available free tools such as Napa, Visual Studio Express or even NotePad that can be used to build your first app.

Through some of the other investments, such as the corporate catalog and the Office Marketplace, Microsoft look to have provided options for both the hardened enterprise user and casual small business user to gain access to either enterprise specific software, or fully tested third party software which can be bought with the simplicity of buying an app for your mobile phone. I am certainly looking forward to seeing the richness of some of the apps being offered through the app store.
